CircuitBrains Basic v1 2
About the CircuitBrains Basic v1 2 PCB
CircuitBrains Basic v1 2 is an open source Microchip SAM PCB design by neubauek, published on GitHub under the MIT license. It is a 2-layer board measuring 25 × 25 mm, with 23 components from 14 distinct parts.
Its main chip is the ATSAMD21E18A-MU, from the Microchip SAM family. Other key parts include the W25Q32JVZPIQ, AP2112K-3.3 and 28SOM. By type, the board carries 9 capacitors, 7 resistors, 4 ICs, 2 LEDs and 1 switch.
From the project
Small form-factor 48-pin castellated pad module. Designed to allow an easy implementation of CircuitPython in maker/hacker projects without the bulk of a large breakout board.

CircuitBrains Basic v1 2: common questions
What microcontroller does the CircuitBrains Basic v1 2 use?
The CircuitBrains Basic v1 2 is built around the ATSAMD21E18A-MU, from the Microchip SAM family.
How big is the CircuitBrains Basic v1 2 PCB?
The CircuitBrains Basic v1 2 measures 25 × 25 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CircuitBrains Basic v1 2?
23 components, from 14 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the CircuitBrains Basic v1 2 design files?
From the neubauek/CircuitBrains repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the CircuitBrains Basic v1 2 design in my own project?
Yes, under the terms of its MIT license, which neubauek chose for the repository.
Can I test firmware for the CircuitBrains Basic v1 2 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
